心率指心脏每分钟搏动的次数, 它能够反映心脏的工作状态。正常心率决定于窦房结的节律性, 成人静息时约60～100 次/ min , 平均约75次/ min。心率可因年龄、性别及其他因素而变化。初生儿心率约130 次/ min , 随年龄增长而逐渐减慢, 至青春期乃接近成人的心率。女性心率比男性稍快 运动员心率较慢。成人安静心率超过120 次/ min 者, 为心动过速 低于40 次/ min 者为心动过缓。心率受植物性神经和体液因素调节。-Heart rate means the number of pulse per minute, it can reflect the work of the state of the heart. Normal heart rate determined by the rhythm of the sinoatrial node, resting adult is about 60 ~ 100 times/min, an average of about 75 times/min. Heart rate may be due to age, gender and other factors change. Heart rate of newborn infants of about 130/min, growth has gradually slowed down with age, to adolescence adult heart rate is near. Women slightly faster rate than men athletes slow heart rate. Quiet adult heart rate over 120 times/min, and for the tachycardia less than 40 times/min for bradycardia. Heart rate by the plant regulate neural and humoral factors.

本分布式小区智能网络模型采用符合现场总线(Fieldbus)要求
的CAN技术，以带CAN总线端口的主控机和单元控制器CAN端接口构成的
CAN网络层，下层为由带RS485端口的住户采集器和单元控制器RS485端
接口构成了RS485网络层，向上则利用PC机连接CAN网络层，作为智能
化小区管理中心，从而基本实现智能小区管理、控制、报警、信息采
集和自我检测的功能。
本文从智能小区、现场总线、CAN技术到“CAN+RS485”双底层网
络模型的软、硬件研究，较为详细的介绍了其设计、调试运行和期间
各种问题的解决。
